One is that you're sacrificing something when you're not your authentic self.
The other is that communication is a two-way street, and people who invest the resources in finding their audience closer to where they are are making their audiences' lives easier, and the attention economy rewards them for that.
I note that most of the YouTube science educators I watch wear makeup, for example (unless they don't show their face at all). And they space their updates to make for a regular-ish pulse of content.
